Hi Richard, well i wish i had good news for you but i also purchased a tv tuner for my 1730 with xp pro only to find out from Dell that that tuner does not work with XP pro only Media center or Vista (Windows issue not hardware).

The good news was while i was finding this out with dells tech support the tech sent me to , http://www.snapstream.com/ which is software that does TV tuning and is the very best on the market. Now i did have to buy the software myself but Dell compensated me (i financed my computer and they deducted the price i payed for the snapstream in full instantly over the phone)

Trust me it was a great deal i ended up more or less getting a TV tuner for free and the best PVR software on the market.

PS: Note that Snapstream comes with a free remote that does more then change the channels (pictures media etc)

snapstreams "Beyond TV" is the program and it supports hundreds of TV tuners. its the software and drivers that windows XP doesnt have and that windows media center does (not the same similar and better) Windows XP just doesnt do TV tuners unless its there media center version which you cant buy or upgrade to anymore and is OEM only and is discontinued
